This is the amazing Discovery Science Channel video documentary Tank on the Moon (2008) which reveals the secret space programs of the former Soviet Union who sent landrover robots on the Moon. During the 1960s, the United States and the Soviet Union were engaged in a feverish competition to be the first to set foot on the moon. We know who won this race, but less about a secret chapter. The Soviets many not have sent a man to the moon, but they successfully guided two small robots by remote control from the earth. For 16 months between 1970 and 1973, these "Lunokhods" traveled more than thirty miles over the moon's surface. With the declassification of the former USSR space archives, along with recollections by several of the key participants in the Lunokhod program, the true story of the Russian lunar robots can finally be told. 45 min. long. A must see for everyone.
